Not bad at all

I really like the energy that you've got going in this. As it moves on, it definitely settles into a nice groove. The only issue I have with it is what the previous poster said about it. That Eb on the F9/A just doesn't sound strong though. It wouldn't sound so jarring if it was over an F and not an A because you get the tritone clash between the melody and the bass.

Also, looking over what the chord progression is, I would have to say that it's actually more in C than it is in F. Reason being that you go from a C to a Cmaj7, which would be the dominant of F. In order for it to work as being in F, you'd have to go down to a C7 instead of a Cmaj7. I think (and this is just my opinion) that a less jarring chord progression for it would be C-Cmaj7-Bb-F-F/A-Fadd9/A-Bb-F. So basically the same thing, only getting rid of that seventh on the F9 (which is actually what's making it seem like it's changing key, because it is. You're hitting a V7-I with that F9-Bb).

Other than that, great job. (Sorry for the ridiculously nitpicky review. The song is great, so the nitpicky details are all that needed to be said)

Interesting...

I like this, but its a little out of the ordinary. You're changing the key so often (The arp and bells seem to mix minor keys with major ones frequently in the melody) that it sounds like its... fluctuating... a little too much. At parts it sounds fantastic, the bells and piano give a really nice atmosphere to the piece. It is quite repetitive, it sounds like it could be background music in some kind of point and click mystery game or maybe in a credit sequence.
Anyway, the song itself is very well done. It sounds professional and clean, its just the thing about the keys that I mentioned earlier thats getting to me a bit.
Great song, thiugh! :P
